Support Requests in Trac
by Marshall Clow 18 Mar '08

18 Mar '08

As we get close to the 1.35 release, I'd appreciate it if the people with open "Support Requests" in Trac (or anyone who wants to help out!) take a look at them and resolve them - or set a milestone for them to be resolved. There are a few requests for support from 2005 and 2006 - those people have been waiting a long time! Thanks! Request #982 "x64 documentation for windows" <http://svn.boost.org/trac/boost/ticket/982 > has a milestone of "Boost 1.35.0" - anyone know what's up with that one? 2 vladimir_prus 2 az_sw_dude 1 nobody 1 no-maintainer 1 jsiek 1 johnmaddock 1 djowel 1 dave 1 anthonyw 1 agurtovoy 1 None None 982 x64 documentation for windows agurtovoy 816 duplicat initial members -> erase_key postcond. fail anthonyw 1053 Error using boost::mutex and C++/CLI az_sw_dude 605 support new 2007 DST rules for timezone db az_sw_dude 614 new timezone db file for #1471723 - 2007 DST support dave 1262 [Boost.Iterators] Reasoning for boost::pointee<> not supporting back_insert_iterator? djowel 1221 Section names may cause html names to be too long johnmaddock 1636 Bug in regex? jsiek 580 Max Flow Algorithm no-maintainer 426 lambda vs pure virtual functions nobody 597 Non-basic-source-character-set characters conflict with MSVC vladimir_prus 1132 program_options documentation error. vladimir_prus 850 program_options strips off escaped quotes in some situations -- -- Marshall Marshall Clow Qualcomm, Inc. <mailto:mclow@qualcomm.com> The famous British scientist, Lord Kelvin, said: "When you measure what you are speaking about and express it in numbers, you know something about it, but when you cannot (or do not) measure it, when you cannot (or do not) express it in numbers, then your knowledge is of a meagre and unsatisfactory kind."

[TR1] Hash test failures on VC9
by Richard Webb 18 Mar '08

18 Mar '08

A couple of the TR1/Hash tests (http://tinyurl.com/3bjkrv, http://tinyurl.com/3cud5g) are failing on VC9 due to a bug in the MS libraries (see http://tinyurl.com/2vekxc for details). Do those tests need to be marked as expected failures? Thanks, Richard Webb

[1.35] Serialization shared_ptr_132 headers cause compilation error with g++ 4.1.0
by Clif Houck 18 Mar '08

18 Mar '08

Hi, I'm trying to update a code base to use boost 1.35 from boost 1.32. From what I've gathered, 1.35's code is frozen and considered to be fairly stable, so I figured that I wouldn't run into any errors caused by boost, just general changes that occurred between 1.32 and 1.35. Instead, it looks like I've definitely run into a bug being caused by 1.35, in particular, the serialization headers for shared_ptr. The following code: #include <boost/serialization/shared_ptr_132.hpp> #include <boost/serialization/shared_ptr.hpp> int main() { return 0; } Causes the following errors: g++ what.cc -o what -I /usr/local/include/boost-1_35/ -lboost_serialization-gcc41-mt-1_35 /usr/local/include/boost-1_35/boost/serialization/shared_ptr.hpp: In function ‘void boost::serialization::load(Archive&, boost::shared_ptr<U>&, unsigned int)’: /usr/local/include/boost-1_35/boost/serialization/shared_ptr.hpp:123: error: ‘null_deleter’ is not a member of ‘boost::archive::detail’ /usr/local/include/boost-1_35/boost/serialization/shared_ptr.hpp:123: error: ‘null_deleter’ is not a member of ‘boost::archive::detail’ /usr/local/include/boost-1_35/boost/serialization/shared_ptr.hpp:123: error: template argument 2 is invalid /usr/local/include/boost-1_35/boost/serialization/shared_ptr.hpp:123: error: expected `>' before ‘*’ token /usr/local/include/boost-1_35/boost/serialization/shared_ptr.hpp:123: error: expected `(' before ‘*’ token /usr/local/include/boost-1_35/boost/serialization/shared_ptr.hpp:124: error: expected primary-expression before ‘>’ token Looking at the documentation included with 1.35 says to retain backwards-compatibility for 1.32's shared_ptr by including both headers in the order I have included them, so I'm at a complete loss. I must retain compatibility with shared_ptr from 1.32 since there is a lot of serialized data floating around from 1.32, and its not feasible to find all of it and convert it mechanically. I hope someone can lend a helping hand. Thanks, Clif Houck

[1.35.0] Links to version history?
by Beman Dawes 18 Mar '08

18 Mar '08

The version history for 1.35.0 is currently located at http://beta.boost.org/users/history/2008-01-23-version_1_35_0. Presumably that will translate to http://www.boost.org/users/history/2008-01-23-version_1_35_0. Why is the date part of the version name? That creates a problem for links from the release, since they have to be changed if the date changes? Would it be possible to change the location to plain http://www.boost.org/users/history/version_1_35_0? Presumably the same pattern should be followed for subsequent releases. Thanks, --Beman

[threads|interprocess] thread_locking_policy and process_locking_policy
by vicente.botet 18 Mar '08

18 Mar '08

Hello, I'm defining a class Locally Unique Identifier (see http://lists.boost.org/Archives/boost/2008/03/134088.php) that has a locking policy. This locking policy needs to define a mutex_type and a scoped_lock types. This could be null_locking_policy for monothreaded usage, thread_locking_policy for multi-threaded access and process_locking_policy for multi-process access. The problem is that when I try to initialize the scoped lock with a try_to_lock the types and variables are differents, even if both mùean the same. And so I need to add a function try_to_lock in the policy. struct thread_locking_policy { typedef boost::mutex mutex_type; typedef boost::mutex::scoped_lock scoped_lock; static const boost::try_to_lock_t try_to_lock() {return boost::try_to_lock;} }; struct process_locking_policy { typedef boost::interprocess::interprocess_mutex mutex_type; typedef boost::interprocess::scoped_lock<mutex_type> scoped_lock; static boost::interprocess::detail::try_to_lock_type try_to_lock() { return boost::interprocess::try_to_lock; } }; IMO we need to armonize the threads and interprocess synchronization interfaces. I don't know where these types and variables could be, but we need that both libraries use the same type and variable. Anyway, these trivial classes will be redone by each user defining a class that manage the synchronization in a wide context. Is there an interest in these locking policies classes. We can add recursive_thread_locking_policy and recursive_process_locking_policy . Where these classes could be placed. Why not in an new boost/sync directory? Please, let me know if there is a better solution already present on boost. Regards _____________________ Vicente Juan Botet Escriba

Boost Selected for Google Summer of Code 2008
by Jeff Garland 18 Mar '08

18 Mar '08

For the third year in a row Boost has been selected as a mentoring organization for Google Summer of Code. If you're a student this is a great opportunity to contribute to Boost and make a few dollars over the summer. If you're interested here's some links to get you started. http://code.google.com/opensource/gsoc/2008/faqs.html http://code.google.com/soc/2008/boost/about.html We have a few project ideas at: http://www.crystalclearsoftware.com/cgi-bin/boost_wiki/wiki.pl?Google_Summe… but, if you've got your own idea that's fine too. Best to put your ideas out on the development list for writing an application -- that's the best way to be sure the mentors think your project has merit. Here's some important dates to keep in mind: March 24: ~12 noon PDT / 19:00 UTC Student application period opens. March 31: 5:00 PM PDT / 00:00 UTC April 1, 2008 Student application deadline. Full timeline is here: http://code.google.com/opensource/gsoc/2008/faqs.html#0.1_timeline Jeff

BoostCon 2008 -- Session Announcement
by Jeff Garland 17 Mar '08

17 Mar '08

I'm happy to announce that the preliminary 2008 BoostCon program is on the web site. http://www.boostcon.com/program/sessions I'm quite pleased and excited with the program. We have tutorials and lectures on many core Boost libraries with topics including threading, serialization, networking, C++0x features, high performance generic programming, text processing, and more. We will also have a new 'Library in a Week' workshop to extend Boost.Algorithm. A new feature this year, based on feedback from last year, will be Author's Corner sessions where library authors discuss and answer questions about their libraries. And, finally, Bjarne Stroustrup with the keynote address. We hope to have the final program and schedule completed shortly. Note that while these sessions represent the bulk of the program we have a few more sessions in the works and are still looking for a couple more sessions to fill out the program. So, if you've been thinking of submitting a session please do it as soon as possible. http://www.boostcon.com/program/call-for-sessions Thanks, Jeff
